Problems solved by technology

The existing horizontal ladder requires the operator to carry the insulating transmission rope for high-altitude transmission during use. This method has the following disadvantages: first, the operator needs to carry the insulation transmission rope when climbing the pole tower, which has a relatively large safety hazard; When using the transfer rope for transfer, there are many operators who need to participate, which brings certain difficulties to the operation organizers; third, when the horizontal ladder reaches the designated position of the insulation repair tower, it needs to be manually tied, and the operation time is longer

Embodiment 1

[0024] Such as Figure 1-3 As shown, the suspension bridge type insulating horizontal ladder provided in this embodiment includes a horizontal ladder body and a rotating fixed body installed on the emergency repair tower.

[0025] The rotating fixed body includes an upper horizontal plate 7 and a lower horizontal plate 10, two fixed columns 9 are arranged between the upper horizontal plate 7 and the lower horizontal plate 10, and fixing columns 9 are arranged on the left and right sides of the upper horizontal plate 7 and the lower horizontal plate 10. Fixing part 8 on the vertical beam of the repair tower. It should be noted that the upper transverse plate 7 and the lower transverse plate 10 can be fixed on the vertical beam of the emergency repair tower through the fixing part 8 using bolts, which is convenient for installation.

[0026] The horizontal ladder body includes a first vertical bar 1, a second vertical bar 5 and several cross bars 2 arranged between the first ve...

Embodiment 2

[0030] Such as Figure 4-6 As shown, on the basis of the above embodiments, the chain hoop 3 includes an upper chain plate 301 and a lower chain plate 302 , and several elastic rollers 12 are arranged between the upper chain plate 301 and the lower chain plate 302 . At the same time, the elastic roller 12 is provided with a T-shaped limit block 13 near the side of the fixed post 9; Limiting grooves are provided on the adjacent sides of the cylinder 901 and the lower cylinder 902 ; a T-shaped limiting space adapted to the T-shaped limiting block 13 is formed between the upper cylinder 901 and the lower cylinder 902 .

[0031] During installation, first fix the upper horizontal plate 7 of the rotating fixed body on the vertical beam of the emergency repair tower, then insert the T-shaped limit block 13 of the chain hoop 3 into the limit groove of the upper column 901, and then insert the lower column Body 902 is buckled and fixed on the vertical beam of the emergency repair tow...

Abstract

The invention discloses a suspension bridge-type insulation horizontal ladder. The suspension bridge-type insulation horizontal ladder comprises a horizontal ladder body and a rotation fixing body, wherein the rotation fixing body is arranged on a repair tower and comprises an upper horizontal plate and a lower horizontal plate, two fixed posts are arranged between the upper horizontal plate and the lower horizontal plate, fixed parts are arranged at left sides and right sides of the upper horizontal plate and the lower horizontal plate and are fixed on a vertical beam of the repair tower, thehorizontal ladder body comprises a first vertical rod, a second vertical rod and a plurality of horizontal rods, the plurality of horizontal rods are arranged between the first vertical rod and the second vertical rod, one end of each horizontal rod is fixedly connected with the first vertical rod, the other end of each horizontal rod is connected with the second vertical rod in a sliding way, chain hoops are fixedly connected with bottom ends of the first vertical rod and the second vertical rod and can be bonded with the fixed posts, fastening blocks are arranged at two ends of the chain hoops, and fastening holes are formed in the fastening blocks. The safety benefit is provided, the working difficulty is reduced, the working time is saved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to an insulating horizontal ladder, in particular to a suspension bridge type insulating horizontal ladder. Background technique [0002] With the development of economy and society, all kinds of electricity customers have higher and higher requirements for the continuous supply of electricity. On the other hand, various hidden risks faced by transmission lines are also multiplying, especially in special weather such as flood season. . It is a fast and effective way to restore power transmission by using insulation repair towers to erect tower collapse accidents of transmission lines caused by natural disasters. After the insulation emergency repair tower is erected and supports the wires, the operator enters the wires, and uses the horizontal ladder to install the relevant hardware by using the equipotential operation method. The existing horizontal ladder requires the operator to carry the insulating transmission rope for high...
